Pertamina began replacing kerosene with LPG in November 2007, and reportedly hopes to convert six million families across Indonesia to the cheaper fuel by the end of 2008.
A large number of agencies are understood to have been invited, including Saatchi & Saatchi and OgilvyAction which holds Pertamina's below-the-line business.
Indonesia has been bedeviled by kerosene shortages in recent years amid allegations that Pertamina has been withdrawing stocks of the fuel to drive conversion to LPG.
